So I thought it made sense to let the guy know, that my SO isn't lying, I am in fact ok with it.
It does make sense for you to verify to him AFTER she sets that up with him. Just like YOU have set it up before when you are the dating person.
me always having to have them talk to my SO so she could explain.
SHE has him talk to YOU so you can explain. She makes first contact and refers him to you for the verify. That's why I stated previously that I assume this came about that way in that order.
Are you saying it came about the other way? You told a man she crushes on that you are cool with him having a casual sex or poly relationship with her without
her blessing or knowing you were going to do that? She didn't initiate first contact?
Could you clarify that please? How exactly did this conversation with him come about?
